Re: the lowest natural sound yet detected

Thanks Walt;

Brian is also right I think.

If the sound is able to propagate through space, it would be a very thin
sound.  Don't know if it is a sound or not.  But I suppose that if you said
it was one atom or molecule bumping another in an orderly fashion and we
assume enough impetus or energy to carry each and every molecule or atom a
long way it would be possible.

Either that or a real thick dust cloud.

At what percentage of atmospheric pressure, or however else you want to
measure it, does sound start to "not do well"?
